I bought myself a lovely Dell U2311h monitor for Christmas. Great monitor, 23'', IPS, good response times, no input lag, solid build. More importantly, this monitor has a great pivot function that gives you 1920 vertical pixels for trolling on Phoronix - perfect!
Unfortunately, this is where the problems start.
First issue: Nvidia's blob doesn't support rotation on dual head setups (you can either rotate no monitor or all monitors). Ok, I'll remove my old CRT, no big loss.
Second issue: if you keep a single monitor and rotate it, the blob stops vsyncing. Completely. My lovely desktop marred by lines and squares. The horror!
I tried both xrandr and the 'Option "Rotate" "CCW"' in xorg.conf. Same result: no vsync (and significantly faster 2d). Affects both Compiz and KWin (Metacity never had vsync so it doesn't count). I tried Nouveau and the situation is actually better there, the vsync failure is smoother - but it still occurs.
My question: is it possible to get vsync on a 9500GT when using a rotated monitor? Either Nvidia or Nouveau driver is fine with me - but if this cannot work, I'll swap in my Ati card.
FFS, Nvidia, your Windows and Mac OS X drivers vsync perfectly when rotating (and support mixed rotations in dual-head). Why did you drop the ball so hard on Linux?
